Description

Coumaphos-D10 CAS NO 287397-86-8 is a deuterated analog of the organophosphate insecticide coumaphos, specifically designed for use as an internal standard in analytical chemistry. This high-purity, isotopically labeled compound is critical for ensuring the accuracy and reliability of quantitative mass spectrometry analyses, particularly in residue testing and environmental monitoring. It is an essential tool for analytical laboratories in the agrochemical, environmental science, and food safety sectors, where precise quantification of coumaphos is required.

Application

• Internal Standard for Mass Spectrometry (MS): Primary application as a stable isotope-labeled internal standard for the accurate quantification of coumaphos via LC-MS/MS and GC-MS methods.
• Residue Analysis in Food Safety: Used in method development and routine testing to monitor coumaphos residues in honey, livestock products, and other agricultural commodities to ensure compliance with Maximum Residue Limits (MRLs).
• Environmental Monitoring: Enables precise tracking and quantification of coumaphos and its metabolites in soil, water, and wastewater samples for environmental impact studies.
• Veterinary Pharmaceutical Research: Supports pharmacokinetic and metabolism studies of coumaphos in animal health applications.
• Method Validation and Quality Assurance: Serves as a critical component in the validation of analytical methods according to guidelines like SANTE/11312/2021, ensuring data integrity and regulatory compliance.
• Reference Material for Calibration: Used to prepare calibration curves with high precision, correcting for matrix effects and instrument variability in complex samples.

Quality Control

Every batch of Coumaphos-D10 is manufactured and analyzed under strict quality systems to guarantee the isotopic purity and chemical integrity required for trace-level analysis. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as isotopic enrichment (typically ≥98 atom % D), chemical purity (by HPLC), and confirmation of structure (by NMR and MS). Our quality commitment ensures the material meets the stringent demands of accredited analytical laboratories operating under ISO/IEC 17025, GLP, or similar frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This product is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere after each use to maintain stability and prevent degradation. Keep away from strong bases and oxidizing agents.
